Radium Extra Range In-line Fuel Pulse Damper Kit -6 AN 20-0200-06
 
Size: -6 AN. Included: Anodized/laser engraved aluminum top, R=range or XR=extra range, Anodized aluminum body threaded for -8AN ORB fittings, Anodized aluminum O-ring sealed adapter fittings, selectable size, Stainless steel M6 mounting bolts and nuts, Rubber vacuum hose, 4mm ID, Vacuum hose Y-fitting. The opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as "stumbling", that are difficult to tune out.
Notes:FPD-XR base pressure requirement = 43 - 78psi (static) The ranges above are base static fuel pressures only. Any dynamic fuel pressure created by a rising-rate FPR outside of this range is acceptable, but only when the base "static" fuel pressure is set within these ranges and the vacuum/boost reference line is hooked up
 
 
Features
The kit features an anodized aluminum housing with a large 0.69" center bore that uses two in-line inlet/outlet ports that are machined with 3/4"-16 UNF threads for 8AN ORB fittings
Depending on the size of the fuel feed hose used, there are 3 kits to choose from which include different male adapter fittings (-6AN, -8AN, -10AN)
These fittings seal to the billet housing using Viton O-rings
Using the supplied M6 bolts/nuts, the FPD kit can be mounted at any possible angle including upside down
